SPOKE-TENON CUTTER.

SPECIFICATION forming part of Letters Patent No. 481,469, dated August23, 1892.

Application filed October '7, 1891. Serial No. l08,000. (No model.)

T0 all whom t may concern:

Be it known that I, ABsALoM BRUNER, of Arkoe, in the county of Nodawayand State of Missouri, have invented certain new and useful Improvementsin Spoke-Tenon Gutters; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use 1t,reference being had to the accompanying grawingawhich form part of thisspecifica- My invention relates to an improvement in Spoke-tenencutters; and it consists in certain novel features of construction andin the combination and arrangement of parts,which will be fullydescribed hereinafter, and more particularly referred to in the annexedclaim.

The object of my invention is to construct a cheap and convenient meansfor cutting spoke-tenons, by the use of which all spokes on the sameWheel will have tenons of equal size. This work is accomplished by amachine which is clamped to the spoke during the operation of cutting,thus holding the machine in one position and preventing any uneven orirregular cutting which so often occurs in hand-tools ordinarily usedfor this purpose.

Referring to the accompanying drawings, Figure lis aperspective view ofmy improved machine. Fig. 2 is a detached view of the portion which isclamped to the spoke.

Before the machine is brought into use the spokes are all placed in thehub of the wheel in the position they will occupy when the wheel iscompleted. The spokes being thus secured, their outer ends are extendedin a rigid manner, ready for the tenons to be cut thereon.

A represents a plate, Which is clamped to the spoke and which isconstructed with a concave lower face to iit the curvature of the spoke.This plate is bent outward between its ends, as shown, and provided witha vertical opening, through which passes the bolt B, having ring C onits lower end. The spoke is passed through this ring and is drawn upagainst the plate A and clamped thereto by the said ring and bolt. Theinner end of the plate A is turned outward and provided With slot D, andformed on its vertical edges are the flanges E.

F represents a plate having an outwardlyturned end F,Which is slotted,as shown, and which is clamped to the corresponding end of the plate A,between the flanges E, by clamping-bolt G. This plate F extends outwardin a line with plate A, and has its outer end bent to form a bearing forthe outer end of shaft H. Aslot I is formed in the said plate, andadapted to move therein is the journalpost J, which forms a bearing forthe inner end of thev said shaft. The end of the said post is extendedthrough the plate F, and loosely mounted on the said extended end is thelever K, the outer end of which is pivoted to the arm L, which ispivoted at its inner end to the upper side of the plate F. The oppositeend of the lever K is formed into a handle M for moving` the said leverback and forth, moving with it the post J through the slot I.

The shaft H is provided with two shoulders N N on its inner end onopposite sides of the post J, so that when the latter is moved the shaftis also moved correspondingly.

Mounted on the inner end of the shaft His the hollow head O, constructedwith a slot P and a projection Q at one side of the said slot. Securedat an angle to this projection is the slotted adjustable knife R, whichmay be so adjusted as to cut a tenon of any desired size. The inner endof the shaft H is squared and the end of the head O constructed with acorrespondingly square recess, into which the said square end of theshaft fits. The head is adjustably secured by the setscrew S, and thisadjustment is useful in regulating the length of the tenon it is desiredto cut. The tenon as it is cut enters the hollow head O, and the end ofthe shaft H acts as a stop and prevents the knife from running anyfarther on the spoke.

In operation the plate A is clamped to the spoke near its outer end, asbefore described. The cutter-head O being thus in line with the spoke,it is run up so as to engage therewith by means of the post J and leverK. The shaft is then revolved by means of the crank F and as thecutter-head is being pressed against the spoke by the lever K as theshaft IOO is revolved the knife cuts inward, yielding to the pressure onthe lever, and thus the tenen is formed.

The machine is very simple and easily op- 5 erated and its work is of asuperior-quality,

1o spoke.

Spokes of different sizes may be cut with equal facility by sim p15adjusting the plates A Fin relation to each other by means of theirslotted meeting ends until the center of the 15 spoke has been broughtin a line with the center of the cutter-head.

Having thus described my invention, I elaim- The combination of alongitudinally-slotted zo support, a projecting bearing formed byturning the rear end of the support outward, a

clamp-section formed by turning the inner end of the support in thereverse direction,a movable post having a head which projects throughthe slot of the support, a shaft carrying a cutterhead journaled in thesaid post and outtnrned bearing, being adapted to move with the former,a lever secured between its ends to the projecting head of the post, a.link secured at one end to the outer end of the 1ever and its oppositeend to the slotted support, a spoke-grasping member, and a proj eetionthereon which is adapted to be secured to the said clamp-section on theslotted support, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ABSALOM BRUNER.
